(c1. roe-n This invention relates to the art of prepared roofing andmore particularly to that class of roofing which is of the shingle type and bears apattern having for its purpose to cause such roof 6 ing to have'an appearance similar to tile roofing. The present invention has for its object to provide roofing per se possessing certain'novel characteristics hereinafter described. I

In the art to which the invention particularly relates prepared roofing consisting, generally, of a strip of suitable paper known as wool-felt paper, which is impregnated and coated with an asphaltic compound and is covered on one face with granulated stone of uniform color, known as grit, is given the appearance of .a shingle or tile roof by applying to the grit coated surface a pattern imitative of the appearance of shingle or tile roofs, the pattern being usually composed of heavy stripes of black to contrast sharply with the light colored grit. A later development consists in cutting a patterned strip of this roofing a medial variated line to produce two strips which are laid in relativelyoverlapped position with the variated edges in staggered relation to better producethe impression or better imitate a tile roof.

Heretofore attempts have been made to out such patternedstrips by machines along a variatedpattern line in order that the variated edges of the resulting pair of strips may be bordered by an appreciable black edging but these attempts have failed by reason of the dimculty involved in naming this coarse and fairly inflexible material through a cutting ma- 35 chine with accuracy, the usual result of such attempts having been thatthe line of severance at one end of the roofing strip was wholly. out

of register with the variated pattern stripe at at least one end portion'of the strip. To produce marketable strips having variated edges bordered by such a black line from a patterned strip having a medial variated pattern stripe, the line of severance must be midway between the side edges of said stripe. v The present practice is to impregnate and coat the paper strip with asphalticcompound and while the coating is still very plastic to apply the grit and then allow the material to cool and set, then apply the pattern stripes and thereupon pass the strip through the cutting machine,

these operations being in many instances successive and continuous and being followed by rolling up and cutting 'the strip into given lengths, the cutting machine serving only to F deeply score but not to *completely sever the strip in order that the same may be rolled up.

' Manufactures of this type of roofing use various methods of rendering the paper weatherproof. In many instances the paper is first passed through a vat of an oily substance which, 30

easily penetrates, is then covered with an' asphaltie compound on one 'or both faces and thereafter goes through the remaining steps above described. In such treatment the asphaltic coating is mainly relied upon to impart the requisite weatherproof characteristics. In severing this type of strip the exposed variated edges'not only lack the deep black color of the asphaltic coating but subject the less weather-. proof body more directly to the action of the elements with the result that the life of the roofing is shortened.

In other instances, the manufacturer impregnates the roofing paper by boiling the same in an asphaltic compound, which, if it completely penetrates the paper, renders the same deep black throughout and more thoroughly weather-proof but such complete penetration is not always effected so that upon exposing a severed edge of such roofing the unimpregnated portion will ab-' 30 sorb moisture and'rapidly deteriorate.

Fig. 8is a sectional view on the line 88 of Fig. 7.

Fig. 9 is a-view similar to Fig. 6'showing a different pattern.

10 is a fragmentary detail section of a printing roller constructed to produce-roofing strips of the presentinvention.

Roofing strips are, in'practically all instances,

thirty-two inches wide and sixty feet long, each passing between said roller 1 and a roller 2 dis-.

posed above the same and which bears firmly upon said strip. Disposed in advance of the rollers 1 and 2 are rollers 4 and 5'which serve to guide the roofing. The rollers .1 and 2 are preferably driven and geared to rotate in unison inrespectively opposite directions by suitable gearing. 1

The roller 1 has a pattern face adapted to apply or print uponthe grip face of the roofing strip a pattern in relatively broad stripes, said pattern, in the instance illustrated; being the conventional one shown in Fig. 6 which includes the zig-zag or variated medial stripe 6. The said pattern face consists of ribs 7 whichare suitably equipped midway between their side edges with cutting or scoring blades 8, said blades, in the instance illustrated, being confined to that portion of the roller 1 which imprints upon 'or applies to the roofing the medial variated strip 6. The blade "or blades 8 is of a height somewhatless than the thickness of said strip so as todeeply score without severing the latter so that it may be rolled up and subsequently severed without the use of tools by merely pulling upon opposite side edge portions of the strip.

The blades 8 serve further to collect upon their faces a coating and in the corners formed by-the same and-the ribs 6, fillets of the liquid. This liquid penetrates into the cut or scoring of the strip and coats in whole or in part the opposed walls of the put or scoring respectively which forms the exposed edges of the strip after severance. Thus the resulting product differs from the strip or shingles heretofore cut-from a strip in that the exposed edges of the product are coated with the weather-proof material 9 used' for producing the pattern stripe and also in that the said edges are bordered by pattern stripes of uniform width. k

In the patterns shown in Figs. 6 and 8, straight stripes extend in staggered relation from the apexes of the medial variated stripe toward the side'edges of the strip and while, in the instance illustrated, the blades 8 are not mounted in the ribs for producing said straight stripes, they may obviously be provided to extend to the side edges of the strip if it be desired to score the same so that it may be readily severed to provide shingles. I

For clarity of illustration, the pattern stripes of Figs. 6 and 8 are. not shown in the solid black -elements exposed by the cut.

of Fig. 7 in order that the severance line 10 may clearly show, the roofing strip of Fig. 6 being 1 scoring a strip to which only the pattern stripes 11 'are applied, along the variated line 10, the alternate angles of the latter must register with the said stripes 11. It will be obvious without specific illustration that in such cases the roller 8 but the rib. 7 will be omitted.

It will be readily appreciated that the, illustration and description of the machine used in producing the roofing strips of this inventionis re,- sorted to as constituting the best manner in whichto present a clear description of the product of this invention without limitation of the latter to any particular machine or method of producingthe same.

. I claim as my invention:

1. As an article of manufacture, a strip of pre-- pared roofing bearing an overlaid pattern composed of stripes of a coagulated liquid weather proof material and scored along at least some of the pattern lines in register with the latter for permitting easy severance of said strip to provide therefrom roofing elements, the overlaid material substantially filling the scqrings and providing coatings for the edges of the elements resulting from severance of the strips along the scorings.

2. As an article (if manufacture, a strip of repared roofing bearing an overlaid pattern composed of' stripes of a cbagulated liquid weather proof material and scored along at least some of the pattern lines and midway of the side edges of the latter for permitting severance of the strip into roofing elements, the overlaid material substantially filling the scorings and providing coatings for the edges of the elements resulting from severance of the strip along the scorings, said edges bordered by overlaid stripes of uniform 1 width.

3. As an article of manufacture, a strip of pre-, pared roofing bearing an overlaid pattern composed of stripes of a coagulated liquid waterproof material and. cut longitudinally along at least 1 some of the pattern lines in register with the latter to provide therefrom elongated roofing elements, the overlaid material substantially filling and providing coatings for the edges of the 4. As an article of manufacture, a strip of prepared roofing bearing on the surface thereof, a pattern composed of stripes of a waterproof ma terial of contrasting colorand cut longitudinally 1 willbe equipped with the knife blade or blades along at least some of the pattern lines in register with the latter to provide therefrom roofing elements, the said waterproof material protecting and substantially covering theedges 'of the elements exposed by'the cut.
